Gets the range of values in each row (column) of a matrix.
rowRanges(x, rows = NULL, cols = NULL, na.rm = FALSE, dim. = dim(x),
..., useNames = TRUE)rowMins(x, rows = NULL, cols = NULL, na.rm = FALSE, dim. = dim(x), ...,

rowRanges()
(colRanges()
) returns a
numeric
Nx2 (Kx2) matrix
, where N
(K) is the number of rows (columns) for which the ranges are calculated.
rowMins()/rowMaxs()
(colMins()/colMaxs()
) returns a
numeric
vector
of length N (K).
A vector
indicating subset of rows to
operate over. If NULL
, no subsetting is done.
A vector
indicating subset of columns to
operate over. If NULL
, no subsetting is done.
If TRUE
, missing values are
excluded.
An integer
vector
of
length two specifying the dimension of x
, also when not a
matrix
. Comment: The reason for this argument
being named with a period at the end is purely technical (we get a run-time
error if we try to name it dim
).
Not used.
If TRUE
(default), names
attributes of the result are set, otherwise not.
